Idle air control motor and carbon = stall
I have a 97 GTS with some modifications. It typically idle at 650-700 rpm one day coming back from the store the idle went to 400-450 and the car stalled. It started up fine but had a low idle. Drove it back and parked it.
I am told it is a idle air control motor has carbon on the plunger and I should clean it.
Has anyone had this issue and how do you do it?
